Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood vessels.[2] Cardiovascular disease includes coronary artery diseases (CAD) such as angina and myocardial infarction (commonly known as a heart attack).[2] Other CVDs include stroke, heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, heart arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis.[2][3]

The underlying mechanisms vary depending on the disease.[2] Coronary artery disease, stroke, and peripheral artery disease involve atherosclerosis.[2] This may be caused by high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol consumption, among others.[2] High blood pressure results in 13% of CVD deaths, while tobacco results in 9%, diabetes 6%, lack of exercise 6% and obesity 5%.[2] Rheumatic heart disease may follow untreated strep throat.[2]

It is estimated that 90% of CVD is preventable.[5] Prevention of atherosclerosis involves improving risk factors through: healthy eating, exercise, avoidance of tobacco smoke and limiting alcohol intake.[2] Treating risk factors, such as high blood pressure, blood lipids and diabetes is also beneficial.[2] Treating people who have strep throat with antibiotics can decrease the risk of rheumatic heart disease.[6] The use of aspirin in people, who are otherwise healthy, is of unclear benefit.[7][8]

Cardiovascular diseases are the leading cause of death globally.[2] This is true in all areas of the world except Africa.[2] Together they resulted in 17.9 million deaths (32.1%) in 2015, up from 12.3 million (25.8%) in 1990.[4][3] Deaths, at a given age, from CVD are more common and have been increasing in much of the developing world, while rates have declined in most of the developed world since the 1970s.[9][10] Coronary artery disease and stroke account for 80% of CVD deaths in males and 75% of CVD deaths in females.[2] Most cardiovascular disease affects older adults. In the United States 11% of people between 20 and 40 have CVD, while 37% between 40 and 60, 71% of people between 60 and 80, and 85% of people over 80 have CVD.[1] The average age of death from coronary artery disease in the developed world is around 80 while it is around 68 in the developing world.[9] Disease onset is typically seven to ten years earlier in men as compared to women.[11]

There are many cardiovascular diseases involving the blood vessels. They are known as vascular diseases.

There are also many cardiovascular diseases that involve the heart.
